Product details

What this I²C accelerator does on the bus

Supply current is 200µA typical, low enough that a battery-powered sensor node or portable instrument won't see a meaningful hit to its quiescent budget. The SC-70-6 package (also called SOT-363) takes minimal board area — useful when you're retrofitting an existing layout that has margin trouble on the I²C bus.

That covers office equipment, consumer electronics, lab instruments, and indoor telecom gear. Not the part for an engine bay, outdoor base station, or cold-chain sensor pod — those need the industrial-temperature LTC4311ISC6#TRPBF variant, which extends to -40°C to 85°C.

ROHS3 compliance means the part meets current environmental restrictions for lead and other hazardous substances, simplifying compliance for products sold into regulated markets.

Frequently asked questions

Can LTC4311CSC6#TRMPBF work with a 1.8V supply?

Yes. The supply range is 1.6V to 5.5V, so 1.8V logic buses are within spec. The part will accelerate rise times on a 1.8V I²C bus without needing a separate regulator.

Is LTC4311CSC6#TRMPBF compatible with 5V I²C buses?

Yes. The 1.6V to 5.5V supply range covers 5V logic. The part's output is 2-wire bus, same as its input, so it passes 5V-level signals correctly.

What is the LTC4311CSC6#TRMPBF used for?

It is an I²C bus accelerator that sharpens rising edges on SDA and SCL lines, allowing the bus to drive higher capacitive loads — longer PCB traces, more slave devices, or connectors — while maintaining 400kHz data rate.

When sourcing LTC4311CSC6#TRMPBF, what is the closest functional alternate?

The LTC4311CDC#TRMPBF is the same accelerator in a different package (SC-70-6 vs DFN). Same 400kHz data rate, same 1.6V supply minimum, same single-channel I²C acceleration. The LTC4311ISC6#TRPBF is the industrial-temperature (-40°C to 85°C) version in the same SC-70-6 package.
